The insufficient supply of high-grade pellet concentrate powder resources and the high production cost of pellet are among the important factors restricting the development of the direct reduction process of hydrogen-based shaft furnace. Study on preparing oxidized pellets in hydrogen-based shaft furnace with high-proportion hematite-limonite is of great practical significance for expanding pellet raw material sources and reducing production cost of pellet and direct reduced iron(DRI).Taking a typical hematite-limonite powder(powder G)as the subject,this paper studies the pellet preparation characteristics with it in the grate-rotary kiln process under different proportions(O~ 50%）and the pellet metallurgicalproperties under simulated HYL process conditions,exploring the feasibility of using a high-proportion hematite-limoniteforpreparingoxidizedpelltinhydrogen-basedshaffurnace.Theresultsshowthatduetothepresenceof high-proportion loose and porous goethite, powder G has good grindability, and the finely ground product has a large specisuacarawisenecifopeizigqagreenpelcapardwihitprorrang of O~50%.However,as the proportion of Powder G increases from O to 50%,the thermal stability of the green pellets shows a downward trend; meanwhile,due to the increased porosity caused by the removal of crystalline water at high temperatures,itisnecessarytoappropriatelyincreasetheroastingtemperaturetomaintainpelletstrength.Comparedwth the base case,when 30%~50% of powder G is blended,the reducibility and binding property of the pellets are god,but the low-temperature reduction disintegration performance worsens with the increase in the proportion of powder G,and the reduction swelling rate shows an upward trend. Optimized ore blending is one of the effective measures to produce high- quality oxidized pellet in hydrogen-based shaft furnace with high-proportion hematite-limonite.
